2. Description of the Related Art In a wooden building, as a joining structure where two pieces of timber are joined, there are a joining structure of a column and a beam or a girder, a joining structure of a column and a base, a beam or a girder. Joint structure of horizontal members such as in series or orthogonal direction,
There are various types of joint structures, such as joint structures at the tops of a pair of left and right diagonal members that form a triangular shape of a truss in combination with a joint or a beam. Conventionally, the joining of two pieces of wood in these various joining structures is performed by processing such as chopping and drilling, by joining metal fittings such as nails, bolts and nuts, dowels, flange plates, and by adhesives. Various types are known, such as those using the same.

[0003]

The above-mentioned various types of conventional joints have been developed and adopted for joining general wood, i.e., Muku material, and have given a certain effect. It is recognized. However, this type of joining has recently been attracting attention and is being used for structural joints in large-scale wooden buildings that use structural glued laminated timber for the main structural parts. It is not always satisfactory because it has disadvantages such as the metal fittings being exposed on the outer surface, being unsightly, and having a complicated structure. The main purpose of the present invention is not only for wooden buildings using general timber but also for large-scale wooden buildings using structural glued laminated lumber, without impairing the appearance of the joint structure of the beams and making it extremely simple. An object of the present invention is to provide a column / beam joint structure capable of obtaining a sufficiently satisfactory tightening strength by a structure.

The joining metal fitting c is provided on three sides excluding the short side on one side of the rectangular bottom plate 1, that is, on the short side on the other side and the long side on both sides. Was established,
It forms an integral box with one short side edge side and the top surface open.

[0008] The pillar mounted side wall 2 Tsubahen 2 ₁ at its upper end outside
Is protruding. The beam fitting side walls 3, 3 are provided with wedge guide frames 4, 4 outside the side opening ends thereof, and guide slopes 5, 5 are provided in the wedge guide frames 4, 4 on the side of the column mounting side wall 2. , And as it goes downward, it is provided as an upwardly inclined surface that gradually approaches the column mounting side wall 2 side. The height h of the box-shaped joint fitting c is the same as the height (thickness) h ′ of the beam b, but the width w is the width w ′ of the beam b.
Less than. Reference numeral 6 denotes a bolt insertion hole formed in the column mounting side wall 2 at a required interval.

In the joint fitting c having such a configuration, the bottom plate 1, the column mounting side wall 2, the beam fitting side walls 3, 3, and the wedge guide frames 4, 4 are separately prepared, and they are welded or screwed by appropriate means. Either assembling them or integrally molding them as a whole, whichever is easier.

The pillar a has a flange insertion groove 7 formed in a beam joining portion on a side surface thereof, and a bolt insertion hole 8.
Are disposed so as to coincide with the bolt insertion holes 6 of the column mounting side wall 2 and are penetrated and installed.

[0011] A joint c is attached to the column a as follows. That is, the metal joint c the flange piece 2 ₁ of the column mounting sidewall 2 is inserted into the flange insertion groove 7, the leading end pillars a bolt 9 inserted through the bolt holes 6, 8 from the inside of the junction fitting c It is projected to the opposite side, and a tightening nut 10 is screwed and tightened to the tip thereof, so that the joint fitting c is
(Fig. 3). The head end 9 ′ of the bolt 9 is of course located inside the pole mounting side wall 2.

At the joint end of the beam b, a fitting cavity 12 having substantially the same shape as that of the joint fitting c having the above structure is formed. The fitting air treatment 12 is intended for fitting to the joint fitting c were mounted and fixed to the column a as described above, provided is opened to the joining end face 11 ₁ and the bottom surface 11 ₂ of the beam b and the a bottom plate 1 flat air treatment 13 that the required size and shape to accept the to accept the head end 9 'of the column mounting sidewall 2 and the bolt 9 be open to the joining end face 11 ₁ and the top surface 11 ₃ longitudinal grooves 14 ₁ and longitudinal grooves 14 ₂ , 14 that are continuous with the flat

It becomes 1 ₃ flush, and also, the wedge insertion space s in the guide slopes 5,5 side within the wedge guide frame 4, 4, s is formed (FIG. 4).

Then, driving wedges 15, 15 are driven into the wedge insertion spaces s, s (FIG. 4). This driving wedge 15,
Reference numeral 15 denotes a beam which is sufficiently longer and tapered than the height (thickness) h 'of the beam c.
Moves toward the column a, and the joint end face 11 ₁
Is pressed against the side surface of the column a. This pressure is, when it becomes a perfect, the upper and lower ends of the driving wedge 15, 15 projecting outwardly of the upper surface 11 ₃ and the bottom surface 11 ₂ of the beam c is cut off with a saw.

A cover plate (not shown) is placed on the beam b which has been joined to the column a, and is screwed to the upper end surfaces of the beam fitting side walls 3 and 3 of the joint fitting c. The gap between the joint fitting c and the fitting space 12 can be closed, the portion can be protected, and the connection between the beam b and the joint fitting c can be further strengthened.

Next, a second embodiment shown in FIGS. In the second embodiment, pillar a 'is joined fittings c on its side' rest recess 7 for receiving the posts mounting the side wall 2 of the 'that you are Ho設formed, the beam b' is the joining end face 11 ₁ Flute 1
4 ₁ shall not be formed, joint device c 'is, in that no projecting the Tsubahen 2 ₁ to the upper end of the pillar mounting sidewall 2, different from the first embodiment, other configurations are the first This is the same as the embodiment. Pillar a 'of the joint fitting c' of the second embodiment
The fixing to the first side is performed by fitting the required length of the end on the side where the column mounting side wall 2 is located to the first
It is the same as the method of attaching and fixing the joint fitting c to the column a in the embodiment, and the method of joining the beam b 'to the column a' is not different from that of the first embodiment. Therefore, the same portions are denoted by the same reference numerals and description thereof will be omitted.

Next, a third embodiment shown in FIGS. In the third embodiment, the joining fitting c "has the wedge guide frames 4, 4 inside the beam fitting side walls 3, 3, and the fitting cavity 12 of the beam b" has the widened vertical groove 14. ₃ , 14 ₃
The in that provided in the inwardly widening the flutes 14 _2, 14 ₂ on the inside, different from the first embodiment, other configurations,
The method of joining the beam b ″ to the column a ″ is not different from that of the first embodiment, and therefore, the same portions are denoted by the same reference numerals and their description is omitted to avoid duplication of description.
